Q:" Can you please tell me if the "triple mesh" feature for this electronic fly swatter means that all three are actively charged for zapping bugs, or is it just the center one with two protective screens on each side?"

Answer: Only the center mesh is live: the outside two mesh layers are offered as protection from accidental "shock" if you should touch the mesh with your hand as you might with a tennis racket. Single mesh units will shock on contact with your hand or other body part. Still handle this insect zapper with care.

Using this electronic swatter means no more chasing after annoying flying insects and then having to hit them against a hard surface, splattering bug parts on walls, table, etc. Just push on the button to activate the grid and release to turn it off. Once you make contact with the fly, bee, etc. the insect dies and drops to the ground. Buy a package of three and save!
